Which memory

Which would be better for o/c with an AM3 Asus M4A79XTD Evo?

9-9-9-27 values at 2000MHz
7-7-7-24 values at 1600MHz

Cheers

anyone please?

Well it depends what voltages are needed to achieve those timings and frequencies really. If the 2000Mhz RAM needs much higher volts than the 1600 then you could probably overclock the 1600 to close to the same frequency by increasing the volts and relaxing the timings.

Probably still the 2000MHZ though.

Its the 2 different G.Skill Ripsaws in at the moment. They are both quoted at the same voltage.

Still the 2000Mhz?

In that case the 2000MHZ will definetly give you more possibilities when overclocking and is the better RAM. May not guarantee a better CPU overclock but will give you more options in how you reach it. It will be faster anyway as RAM in its own right although you probably wouldn't notice the difference.

Having just checked the specs of that motherboard I am not even sure that 2000mhz RAM is supported. It appears (at a glance) that 1800mhz is the maximum for that board.

9-9-9-27 values at 2000MHz - 9.0ns - 16,000 MB/s (25% Greater Bandwidth)
7-7-7-24 values at 1600MHz - 8.8 ns - 12,800 MB/s (2.2% Lower Latency)

The first set offer quite a large boost to memory bandwidth, the second set offer a slightly lower latency. *If* the price was right and *if* you are sure its possible to get DDR3-2000 running at full speed on an AMD platform then I think the first set look the best! :cool:
